I think I uninstalled pip by mistake ^^
I ran something like "pip uninstall pip" in CMD and it completely broke, giving fatal errors.
I uninstalled and reinstalled python, added the correct folders back to PATH, but now it's only working via python -m pip XXXX and not by typing pip XXXX...
If I type pip XXX i get an empty row and CMD gives me back the cursor.
How can I recover? I liked pip XXX better and I am sure that the pip folder is in PATH.
It would help greatly to know what version of each you are using and what OS but for a generic answer...
You could try to install it manually:
Vist:
https://pip.pypa.io/en/stable/installing.html
Download:
get-pip.py
python get-pip.py
Make sure your python version matches your pip version. Otherwise you will always have to be specific on your installs. And for sake of simplicity make sure it works fine with just one version of Python installed. Then if that works you can consider having more.
After installing it, if you upgrade your python version make sure you keep it up to date.
I would try something like:
pip install --upgrade --no-deps --force-reinstall
As os version 21.3.1, you can install pip with the one-liner:
python -m ensurepip --upgrade.
See installation of pip doc for details.
I always install packages with the command "python -m pip install " in cmd. Today I got the notification that I am using pip and pip 20.1.1 can be installed by typing "python -m pip install --upgrade pip". I did that and now pip fails to install or uninstall programmes. This is the error message I get when trying to install a new package.
ImportError: cannot import name 'webencodings' from 'pip._vendor' (C:\Users\user\AppData\Local\Programs\Python\Python38-32\lib\site-packages\pip\_vendor\__init__.py)
I am a complete beginner and don't want to mess to much with the pip directory, is there an easy solution for my problem?
It looks like this has been happening with pip 20+ when your "system" pip install gets incorrectly upgraded -- it's honestly pretty messed up that the default upgrade command that pip itself tells you to use does this "wrong" upgrade.
See this issue for a detailed discussion, a bunch of related issues, and some workarounds. This more recent report has a bunch of people reporting the same for pip20.
Potentially the easiest solution is to uninstall it:
python -m pip uninstall pip
Which should bring you back to the "system" pip installation. And then just ignore the warning, or only work inside virtualenvs, where you shuold be able to safely use updated pip.
Another possible workaround is to install an older version manually using the get-pip script:
python get-pip.py pip==19.3.1
Note: If anyone has better advice please feel free to comment / correct me.
I'm trying to install some packages with pip.
But pip install unroll gives me
Command "python setup.py egg_info" failed with error code 1 in
C:\Users\MARKAN~1\AppData\Local\Temp\pip-build-wa7uco0k\unroll\
How can I solve this?
About the error code
According to the Python documentation:
This module makes available standard errno system symbols. The value of each symbol is the corresponding integer value. The names and descriptions are borrowed from linux/include/errno.h, which should be pretty all-inclusive.
Error code 1 is defined in errno.h and means Operation not permitted.
About your error
Your setuptools do not appear to be installed. Just follow the Installation Instructions from the PyPI website.
If it's already installed, try
pip install --upgrade setuptools
If it's already up to date, check that the module ez_setup is not missing. If it is, then
pip install ez_setup
Then try again
pip install unroll
If it's still not working, maybe pip didn't install/upgrade setup_tools properly so you might want to try
easy_install -U setuptools
And again
pip install unroll
Here's a little guide explaining a little bit how I usually install new packages on Python + Windows. It seems you're using Windows paths, so this answer will stick to that particular SO:
I never use a system-wide Python installation. I only use virtualenvs, and usually I try to have the latest version of 2.x & 3.x.
My first attempt is always doing pip install package_i_want in some of my Visual Studio command prompts. What Visual Studio command prompt? Well, ideally the Visual Studio which matches the one which was used to build Python. For instance, let's say your Python installation says Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec 5 2015, 20:40:30) [MSC v.1500 64 bit (AMD64)] on win32. The version of Visual Studio used to compile Python can be found here, so v1500 means I'd be using vs2008 x64 command prompt
If the previous step failed for some reason I just try using easy_install package_i_want
If the previous step failed for some reason I go to gohlke website and I check whether my package is available over there. If it's so, I'm lucky, I just download it into my virtualenv and then I just go to that location using a command prompt and I do pip install package_i_want.whl
If the previous step didn't succeed I'll just try to build the wheel myself and once it's generated I'll try to install it with pip install package_i_want.whl
Now, if we focus in your specific problem, where you're having a hard time installing the unroll package. It seems the fastest way to install it is doing something like this:
git clone https://github.com/Zulko/unroll
cd unroll && python setup.py bdist_wheel
Copy the generated unroll-0.1.0-py2-none-any.whl file from the created dist folder into your virtualenv.
pip install unroll-0.1.0-py2-none-any.whl
That way it will install without any problems. To check it really works, just login into the Python installation and try import unroll, it shouldn't complain.
One last note: This method works almost 99% of the time, and sometimes you'll find some pip packages which are specific to Unix or Mac OS X, in that case, when that happens I'm afraid the best way to get a Windows version is either posting some issues to the main developers or having some fun by yourself porting to Windows (typically a few hours if you're not lucky) :)
It was resolved after upgrading pip:
python -m pip install --upgrade pip
pip install "package-name"
I got stuck exactly with the same error with psycopg2. It looks like I skipped a few steps while installing Python and related packages.
sudo apt-get install python-dev libpq-dev
Go to your virtual env
pip install psycopg2
(In your case you need to replace psycopg2 with the package you have an issue with.)
It worked seamlessly.
I got this same error while installing mitmproxy using pip3. The below command fixed this:
pip3 install --upgrade setuptools
Download and install the Microsoft Visual C++ Compiler for Python 2.7 from https://www.microsoft.com/en-in/download/details.aspx?id=44266 - this package contains the compiler and set of system headers necessary for producing binary wheels for Python 2.7 packages.
Open a command prompt in elevated mode (run as administrator)
Firstly do pip install ez_setup
Then do pip install unroll (It will start installing numpy, music21, decorator, imageio, tqdm, moviepy, unroll) # Please be patient for music21 installation
Python 2.7.11 64 bit used
Other way:
sudo apt-get install python-psycopg2 python-mysqldb
I had the same issue when installing the "Twisted" library and solved it by running the following command on Ubuntu 16.04 (Xenial Xerus):
sudo apt-get install python-setuptools python-dev build-essential
It's a dependency issue.
I tried running the following commands helped me sorting out the dependencies, in my case the dependency was
grpcio
pip3 install --upgrade pip
python3 -m pip install --upgrade setuptools
pip3 install --no-cache-dir --force-reinstall -Iv grpcio==1.36.1
pip3 install pulsar-client==2.7.0
remember you must have python3 installed in your system.
First try:
pip install unroll
For sure not work :)
Then Try:
pip2 install unroll
Still get error Try:
pip3 install unroll
If pip3 Worked then suggest to change configuration to use pip3 as pip because you will get a lot of issues as the modern now is Python3 = pip3 if you execute a script files.
I had the same problem.
The problem was:
pyparsing 2.2 was already installed and my requirements.txt was trying to install pyparsing 2.0.1 which throw this error
Context: I was using virtualenv, and it seems the 2.2 came from my global OS Python site-packages, but even with --no-site-packages flag (now by default in last virtualenv) the 2.2 was still present. Surely because I installed Python from their website and it added Python libraries to my $PATH.
Maybe a pip install --ignore-installed would have worked.
Solution: as I needed to move forwards, I just removed the pyparsing==2.0.1 from my requirements.txt.
I ran into the same error code when trying to install a Python module with pip.
#Hackndo noted that the documentation indicate a security issue.
Based on that answer, my problem was solved by running the pip install command with sudo prefixed:
sudo pip install python-mpd2
For me this worked
python3 -m pip3 install -U pip
you can also try
python -m pip install -U pip
pip3 install --upgrade setuptools
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with -m pip instead of running pip directly.
Use python3 -m pip "command", eg:
python3 -m pip install --user pyqt5
I tried all of the above with no success. I then updated my Python version from 2.7.10 to 2.7.13, and it resolved the problems that I was experiencing.
That means some packages in pip are old or not correctly installed.
Try checking version and then upgrading pip.Use auto remove if that works.
If the pip command shows an error all the time for any command or it freezes, etc.
The best solution is to uninstall it or remove it completely.
Install a fresh pip and then update and upgrade your system.
I have given a solution to installing pip fresh here - python: can't open file get-pip.py error 2] no such file or directory
next installation helps me:
pip3 install cython
This worked for me:
sudo xcodebuild -license
Upgrading Python to version 3 fixed my problem. Nothing else did.
I downloaded the .whl file from http://www.lfd.uci.edu/~gohlke/pythonlibs/ and then did:
pip install scipy-0.19.1-cp27-cp27m-win32.whl
Note that the version you need to use (win32/win_amd-64) depends on the version of Python and not that of Windows.
I had this problem using virtualenvs (with pipenv) on my new development setup.
I could only solve it by upgrading the psycopg2 version from 2.6.2 to 2.7.3.
More information is at https://github.com/psycopg/psycopg2/issues/594
I faced the same problem with the same error message but on Ubuntu 16.04 LTS (Xenial Xerus) instead:
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-w71uo1rg/poster/
I tested all the solutions provided above and none of them worked for me. I read the full TraceBack and found out I had to create the virtual environment with Python version 2.7 instead (the default one uses Python 3.5 instead):
virtualenv --python=/usr/bin/python2.7 my_venv
Once I activated it, I run pip install unirest successfully.
try on linux:
sudo apt install python-pip python-bluez libbluetooth-dev libboost-python-dev libboost-thread-dev libglib2.0-dev bluez bluez-hcidump
Had the same problem on my Win10 PC with different packages and tried everything mentioned so far.
Finally solved it by disabling Comodo Auto-Containment.
Since nobody has mentioned it yet, I hope it helps someone.
I had the same problem and was able to fix by doing the following.
Windows Python needs Visual C++ libraries installed via the SDK to build code, such as via setuptools.extension.Extension or numpy.distutils.core.Extension. For example, building f2py modules in Windows with Python requires Visual C++ SDK as installed above. On Linux and Mac, the C++ libraries are installed with the compiler.
https://www.scivision.co/python-windows-visual-c++-14-required/
Following below command worked for me
[root#sandbox ~]# pip install google-api-python-client==1.6.4
Methods to solve setup.pu egg_info issue when updating setuptools or not other methods doesnot works.
If CONDA version of the library is available to install use conda instead of pip.
Clone the library repo and then try installation by pip install -e . or by python setup.py install
upgrading python's version did the work for me.
I have just encountered the same problem when trying to pip install -e . a new repo. I did not notice that the contents of setup.py haven't been saved properly and I was effectively running the command with an empty setup.py.
Hence you may experience the same error message if the setup.py of the target package is either empty or malformed.
I solved it on Centos 7 by using:
sudo yum install libcurl-devel
I'm trying to use PyMySQL on Ubuntu.
I've installed pymysql using both pip and pip3 but every time I use import pymysql, it returns ImportError: No module named 'pymysql'
I'm using Ubuntu 15.10 64-bit and Python 3.5.
The same .py works on Windows with Python 3.5, but not on Ubuntu.
Sort of already answered this in the comments, but just so this question has an answer, the problem was resolved through running:
sudo apt-get install python3-pymysql
Use:
import pymysql
Not:
import PyMySQL
That works for me.
After trying a few things, and coming across PyMySQL Github, this worked:
sudo pip install PyMySQL
And to import use:
import pymysql
If even sudo apt-get install python3-pymysql does not work for you try this:
Go to the PyMySQL page and download the zip file.
Then, via the terminal, cd to your Downloads folder and extract
the folder
cd into the newly extracted folder
Install the setup.py file with: sudo python3 setup.py install
Make sure that you're working with the version of Python that think you are. Within Python run import sys and print(sys.version).
Select the correct package manager to install pymysql with:
For Python 2.x sudo pip install pymysql.
For Python 3.x sudo pip3 install pymysql.
For either running on Anaconda: sudo conda install pymysql.
If that didn't work try APT: sudo apt-get install pymysql.
If all else fails, install the package directly:
Go to the PyMySQL page and download the zip file.
Then, via the terminal, cd to your Downloads folder and extract the folder.
cd into the newly extracted folder.
Install the setup.py file with: sudo python3 setup.py install.
This answer is a compilation of suggestions. Apart from the other ones proposed here, thanks to the comment by #cmaher on this related thread.
To get around the problem, find out where pymysql is installed.
If for example it is installed in /usr/lib/python3.7/site-packages, add the following code above the import pymysql command:
import sys
sys.path.insert(0,"/usr/lib/python3.7/site-packages")
import pymysql
This ensures that your Python program can find where pymysql is installed.
fwiw, for a conda env:
conda install -c anaconda pymysql
For windows or one using google colab, you can try this
!pip install pymysql
import pymysql
sudo apt-get install python3-pymysql
This command also works for me to install the package required for Flask app to tun on ubuntu 16x with WISG module on APACHE2 server.
BY default on WSGI uses python 3 installation of UBUNTU.
Anaconda custom installation won't work.
I had this same problem just now, and found the reason was my editor (Visual Studio Code) was running against the wrong instance of python; I had it set to run again python bundled with tensorflow, I changed it to my Anaconda python and it worked.
Just a note:
for Anaconda install packages command:
python setup.py install
if you are using SPYDER IDE , just try to restart the console or restart the IDE, it works
I also got this error recently when using Anaconda on a Mac machine.
Here is what I found:
After running python3 -m pip install PyMySql, pymysql module is under /Library/Python/3.7/site-packages
Anaconda wants this module to be under /opt/anaconda3/lib/python3.8/site-packages
Therefore, after copying pymysql module to the designated path, it runs correctly.
Another common issue causing the error message to appear is related to conda environments in jupyter notebook and jupyter lab.
After successfully installing a module (pymysql in this case) in one environment, import may seem to fail because the environment has not been correctly registered. To solve this it is necessary to manually add kernels for each environment.
Solution and more details can be found here.
I tried installing pymysql on command prompt by typing
pip install pymysql
But it still dont work on my case, so I decided to try using the terminal IDE and it works.
I ran into the same problem earlier, but solved it in a way slightly different from what we have here. So, I thought I'd add my way as well. Hopefully, it will help someone!
sudo apt-get install mysql-client didn't work for me. However, I have Homebrew already installed. So, instead, I tried:
brew install mysql-client
Now, I don't get the error any more.
You can also visit this lien pip install PyMySQL
You just need to install:
python3 -m pip install PyMySQL
The following pymysql version worked for me:
pip install pymysql==1.0.2
For anaconda user,
I got this error message.
ModuleNotFoundError: No module named 'pymysql'
So tried 'pip install pymysql' but got below.
Requirement already satisfied: pymysql
What worked for me is,
python file.py (NOT py file.py)
I tried importing requests:
import requests
But I get an error:
ImportError: No module named requests
Requests is not a built in module (does not come with the default python installation), so you will have to install it:
OSX/Linux
Python 2: sudo pip install requests
Python 3: sudo pip3 install requests
if you have pip installed (pip is the package installer for python and should come by default with your python installation).
If pip is installed but not in your path you can use python -m pip install requests (or python3 -m pip install requests for python3)
Alternatively you can also use sudo easy_install -U requests if you have easy_install installed.
Linux
Alternatively you can use your systems package manager:
For centos: sudo yum install python-requests
For Debian/Ubuntu Python2: sudo apt-get install python-requests
For Debian/Ubuntu Python3: sudo apt-get install python3-requests
Windows
Use pip install requests (or pip3 install requests for python3) if you have pip installed and Pip.exe added to the Path Environment Variable. If pip is installed but not in your path you can use python -m pip install requests (or python3 -m pip install requests for python3)
Alternatively from a cmd prompt, use > Path\easy_install.exe requests, where Path is your Python*\Scripts folder, if it was installed. (For example: C:\Python32\Scripts)
If you manually want to add a library to a windows machine, you can download the compressed library, uncompress it, and then place it into the Lib\site-packages folder of your python path. (For example: C:\Python27\Lib\site-packages)
From Source (Universal)
For any missing library, the source is usually available at https://pypi.python.org/pypi/. You can download requests here: https://pypi.python.org/pypi/requests
On mac osx and windows, after downloading the source zip, uncompress it and from the termiminal/cmd run python setup.py install from the uncompressed dir.
(source)
It's not obvious to me which version of Python you are using.
If it's Python 3, a solution would be sudo pip3 install requests
To install requests module on Debian/Ubuntu for Python2:
$ sudo apt-get install python-requests
And for Python3 the command is:
$ sudo apt-get install python3-requests
Brew users can use reference below,
command to install requests:
python3 -m pip install requests
Homebrew and Python
pip is the package installer for Python and you need the package requests.
This may be a liittle bit too late but this command can be run even when pip path is not set. I am using Python 3.7 running on Windows 10 and this is the command
py -m pip install requests
and you can also replace 'requests' with any other uninstalled library
If you are using Ubuntu, there is need to install requests
run this command:
pip install requests
if you face permission denied error, use sudo before command:
sudo pip install requests
In my case requests was already installed, but needed an upgrade. The following command did the trick
$ sudo pip install requests --upgrade
On OSX, the command will depend on the flavour of python installation you have.
Python 2.x - Default
sudo pip install requests
Python 3.x
sudo pip3 install requests
On Windows Open Command Line
pip3 install requests
I had the same issue, so I copied the folder named "requests" from https://pypi.python.org/pypi/requests#downloadsrequests download to
"/Library/Python/2.7/site-packages".
Now when you use: import requests, it should work fine.
In the terminal/command-line:
pip install requests
then use it inside your Python script by:
import requests
or else if you want to use pycharm IDE to install a package:
go to setting from File in menu
next go to Python interpreter
click on pip
search for requests package and install it
Adding Third-party Packages to the Application

https://cloud.google.com/appengine/docs/python/tools/libraries27?hl=en#vendoring
step1 : Have a file by named a file named appengine_config.py in the root of your project, then add these lines:
from google.appengine.ext import vendor
Add any libraries installed in the "lib" folder.
vendor.add('lib')
Step 2: create a directory and name it "lib" under root directory of project.
step 3: use pip install -t lib requests
step 4 : deploy to app engine.
Try sudo apt-get install python-requests.
This worked for me.
If you are using anaconda as your python package manager, execute the following:
conda install -c anaconda requests
Installing requests through pip didn't help me.
The only thing that worked for me:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
pip install requests
Facing the same issue but unable to fix it with the above solution, so I tried this way and it worked:-
curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
sudo python2 get-pip.py
python -m pip install requests
For windows just give path as cd and path to the "Scripts" of python and then execute the command easy_install.exe requests.Then try import requests...
I have had this issue a couple times in the past few months. I haven't seen a good solution for fedora systems posted, so here's yet another solution. I'm using RHEL7, and I discovered the following:
If you have urllib3 installed via pip, and requests installed via yum you will have issues, even if you have the correct packages installed. The same will apply if you have urllib3 installed via yum, and requests installed via pip. Here's what I did to fix the issue:
sudo pip uninstall requests
sudo pip uninstall urllib3
sudo yum remove python-urllib3
sudo yum remove python-requests
(confirm that all those libraries have been removed)
sudo yum install python-urllib3
sudo yum install python-requests
Just be aware that this will only work for systems that are running Fedora, Redhat, or CentOS.

These commands are also useful if Homebrew screws up your path on macOS.
python -m pip install requests
or
python3 -m pip install requests
Multiple versions of Python installed in parallel?
You must make sure your requests module is not being installed in a more recent version of python.
When using python 3.7, run your python file like:
python3 myfile.py
or enter python interactive mode with:
python3
Yes, this works for me. Run your file like this: python3 file.py
I have installed python2.7 and python3.6
Open Command Line to ~/.bash_profile I find that #Setting PATH for Python 3.6 , So
I change the path to PATH="/usr/local/Cellar/python/2.7.13/bin:${PATH}" ,
(please make sure your python2.7's path) ,then save.
It works for me.
if you want request import on windows:
pip install request
then beautifulsoup4 for:

or...
python -m pip install requests

python -m pip3 install requests
If all of these don't work, please leave a comment!
How does this work? Depending on the operating system you currently use, the pip command may vary or not work on some. These are the commands you may try in order for a fix.
In case you hit pip install requests and had an output massage of Requirement already satisfied but yet you still get the error: ImportError: No module named requests.
This is likely to happen when you find yourself in a different interpreter/virtual environment.
You can copy and append the path of the module into your working environment.
Note: This path usually comes with the message Requirement already satisfied
Before import requests, you should import sys and then append the copied path.
Example:
Command Prompt:
pip install requests
Output:
Requirement already satisfied: requests in /usr/local/lib/python3.9/site-packages
import sys
sys.path.append("/usr/local/lib/python3.9/site-packages")
import requests
I solved this problem.You can try this method.
In this file '.bash_profile', Add codes like alias python=/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
Type this command in Command Prompt (Windows) or Terminal (Linux/macOS):
pip install requests
My answer is basically the same as #pi-k. In my case my program worked locally but failed to build on QA servers. (I suspect devops had older versions of the package blocked and my version must have been too out-of-date) I just decided to upgrade everything
$ pip install pip-review
$ pip-review --local --interactive
You get an import error because requests are not a built-in module instead, it is created by someone else and you need to install the requests.
use the following command on your terminal then it will work correctly.
pip install requests
Install python requests library and this error will be solved.
I found that my issue was VSCode was reading from the wrong Python Interpreter. This youtube tutorial solved it for me.
If you are using anaconda
step 1:
